چکیده
Abstract Single-photon source in micro- or nanoscale is the basic building block of on-chip quantum information and scalable network. Enhanced spontaneous emission based on cavity electrodynamics (CQED) one key principles realizing single-photon sources fabricated by nanophotonic cavities. Here we mainly review single emitters nanostructures, such as whispering gallery microcavities, photonic crystals, plasmon metamaterials, their hybrids. The researches have enriched light-matter interaction well made great influence source, circuit, information.

Keywords-Silicon photonics; subwavelength gratings; fiberchip coupler; waveguid...
متن کاملQuantum state-controlled directional spontaneous emission of photons into a nanophotonic waveguide
The spin of light in subwavelength-diameter waveguides can be orthogonal to the propagation direction of the photons because of the strong transverse confinement. This transverse spin changes sign when the direction of propagation is reversed. Using this effect, we demonstrate the directional spontaneous emission of photons by laser-trapped caesium atoms into an optical nanofibre and control th...
متن کاملTheory of optical spontaneous emission rates in layered structures.
This paper presents expressions for the optical power and fields radiated by an oscillating dipole in layered structures, with loss or gain, that are easy to evaluate. For structures without loss or gain, it is discussed that the radiated power is a direct measure for the local density of modes, whereas for structures with loss or gain, this correspondence no longer holds due to interaction bet...
متن کاملSpectral analysis based on compressive sensing in nanophotonic structures.
A method of spectral sensing based on compressive sensing is shown to have the potential to achieve high resolution in a compact device size. The random bases used in compressive sensing are created by the optical response of a set of different nanophotonic structures, such as photonic crystal slabs. The complex interferences in these nanostructures offer diverse spectral features suitable for ...
